How to Calibrate Braun Ear Thermometer in 2025

No, I can’t calibrate a Braun ear thermometer at home.
I see three things that sound the same but are different:

• Calibration: Only experts do this.

• Calibration check: I can do this to see if my thermometer works right.

• Resetting: I turn it off and on or take out the battery.

If I want to know how to calibrate braun ear thermometer, I always look at the instructions from the company. They help me keep my readings right. 🧐👍

Calibration Basics

Manufacturer Guidelines

I cannot calibrate my Braun ear thermometer at home.
The company says only experts can do this job. When I read the manual, I see clear steps for using and checking my thermometer, but not for calibration. If I try to fix it myself, I might break it. I always follow the instructions from Braun. They know best! 📝

Tip: I keep my manual in a safe place. When I have a question, I look there first.

Calibration vs. Calibration Check

I used to think calibration and calibration check were the same. They are not! Here is what I learned:

Name	Who Does It?	What Happens?
Calibration	Experts	Adjusts the inside settings
Calibration Check	Me (at home)	Checks if it works right
Resetting	Me (at home)	Turns off and on, or removes battery

• Calibration: Only a pro can calibrate. They use special tools.

• Calibration check: I can do this at home. I compare my thermometer to another one I trust.

• Resetting: I take out the battery or press a button to start fresh.

Note: If my readings seem wrong, I do a calibration check first.

When to Consider Calibration

I think about calibration when:

1. My thermometer gives strange numbers again and again.

2. I check with another thermometer, and the numbers are very different.

3. I see error codes that do not go away after resetting.

If I see these problems, I do not try to calibrate myself. I call Braun or a repair shop. They help me fix it the right way. 🛠️

Remember: Most of the time, I just need to check or reset. Real calibration is rare for home users.

How to Calibrate Braun Ear Thermometer

I cannot really calibrate my Braun ear thermometer at home, but I can do a calibration check. I always want to know how to calibrate braun ear thermometer the right way. Here is what I do step by step:

Calibration Check Steps

Prepare the Device

1. I wash my hands.

2. I put a new probe cover on the thermometer.

3. I make sure the thermometer is at room temperature (not too hot or cold).

4. I check that the batteries are good.

Tip: I wait 30 minutes if I bring the thermometer from outside. It needs time to get used to the room.

Use a Reference Thermometer

• I find another thermometer that I trust.

• I use both thermometers to take the temperature in the same ear, one after the other.

• I write down the numbers.

Check Measurement Accuracy

I look at the numbers from both thermometers. I want to see if my Braun ear thermometer is close to the other one. I use this table to help me:

Parameter	Braun IRT-3020 Ear Thermometer Specifications
Measurement Range	34.0 °C to 42.2 °C
Resolution	0.1 °C
Accuracy	±0.1 °C (37.0–39.0 °C) / ±0.2 °C (other)

If my thermometer shows a number that is more than 0.2 °C different, I know something is wrong. I check again to be sure. I also look at this chart to see the target temperatures and how close my thermometer should be:

Note: If my thermometer is always off, I stop using it and call Braun.

Resetting the Thermometer

Sometimes, my thermometer gives strange numbers or shows a flashing display. I know how to calibrate braun ear thermometer by resetting it. Here is what I do:

Battery Removal

• I turn off the thermometer.

• I open the battery cover.

• I take out the batteries for 10 seconds.

• I put the batteries back in.

• I turn on the thermometer.

Factory Reset

• If the thermometer still does not work, I wait for it to turn off by itself (about 1 minute).

• I turn it on again.

• If I see an error, I let the thermometer rest in the room for 30 minutes. Sometimes, the room is too hot or cold.

Alert: If my thermometer keeps showing errors, I do not try to fix it myself. I call Braun or look in the manual for help.

I always remember how to calibrate braun ear thermometer is not about changing the inside. I just check, reset, and ask for help if needed. I keep my thermometer clean and safe. I use these steps every time I want to know how to calibrate braun ear thermometer at home.

Accuracy Tips

Proper Use

I always use my ear thermometer the right way to get good numbers.
Here is what I do every time:

1. I wash my hands before I touch the thermometer. 🧼

2. I put a new probe cover on before I use it.

3. I pull my ear up and back. This helps the thermometer go in the right spot.

4. I wait a few seconds after turning it on. The thermometer needs to be ready.

5. I put the thermometer in my ear gently. I do not push too hard.

6. I press the button and wait for the beep.

7. I read the number on the screen.

Tip: I always use the same ear for every check. This helps me get numbers that match.

Probe Covers

I never use my thermometer without a probe cover.
Probe covers keep my thermometer clean and safe. Here is why I use them:

• They stop dirt and earwax from getting inside.

• They help the thermometer work better.

• They keep germs away from my family.

I change the probe cover every time I use the thermometer. If I forget, the numbers might be wrong. I keep extra probe covers in a small box. 📦

Good Habit	Why I Do It
Use new cover	Keeps thermometer clean
Throw away old one	Stops germs from spreading

Note: If I run out of probe covers, I buy more before I use the thermometer again.

Room Conditions

I check the room before I use my thermometer.
The room should not be too hot or too cold. If I bring my thermometer from outside, I let it sit in the room for 30 minutes. This helps it get used to the air.

• I do not use the thermometer near a heater or fan.

• I wait if I just came inside from the cold.

• I keep the thermometer in a drawer, not in the sun.

Alert: If the room is too hot or cold, my thermometer might give a wrong number. I always wait for it to feel like the room.

I follow these tips every time. My thermometer gives me good numbers when I do.

Troubleshooting

Inconsistent Readings

Sometimes my thermometer gives me different numbers every time. This makes me feel confused. I want to know what is wrong. Here is what I do:

1. I check if I use a new probe cover each time. Dirty covers can make numbers strange.

2. I make sure I put the thermometer in my ear the same way every time.

3. I wait for the beep before I take it out.

4. I always use the same ear for every check.

5. I let the thermometer rest in the room for 30 minutes if I just brought it from outside.

Tip: If I still get numbers that jump up and down, I try new batteries. Sometimes low batteries make the thermometer act funny.

Error Codes

When I see an error code on my screen, I do not panic. I look at the manual to see what the code means. Here are some common codes and what I do:

Error Code	What It Means	What I Do
POS	Bad position in ear	Try again, put in right
LO	Temperature too low	Warm up thermometer
HI	Temperature too high	Let thermometer cool down
ERR	Device problem	Reset or change batteries

Alert: If the error code does not go away after I reset, I stop using the thermometer and ask for help.

When to Seek Service

I know I need help from Braun or a pro when:

• My thermometer is always off by more than 0.27°C (or 0.5°F) compared to a good thermometer.

• I see big differences, like 1.9°C, between my thermometer and a rectal thermometer.

• I use my thermometer for someone who is very sick, or in a clinic or emergency.

• I need to check temperature all the time for treatment.

• I see error codes that do not go away, even after I reset and change batteries.

Here is a table to help me know when to get help:

When to Get Help	Why It Matters
More than 0.27°C difference	Wrong numbers can make doctors miss sickness.
Using in hospital or emergency	Only pro thermometers are safe here.
Error codes stay	My thermometer may be broken.
Numbers change a lot	I cannot trust the thermometer.

Note: I never try to fix the inside of my thermometer. I call Braun or a repair shop. This keeps me and my family safe. 🛠️😊

Maintenance

Cleaning

I always clean my Braun ear thermometer to keep it safe and working well. 🧼

Here is what I do:

1. I take off the used probe cover and throw it away.

2. I use a soft, dry cloth to wipe the outside of the thermometer.

3. If I see dirt, I use a little rubbing alcohol on the cloth. I never use water or put the thermometer in the sink.

4. I never touch the lens with my fingers. If the lens looks dirty, I use a cotton swab with a drop of alcohol and clean it very gently.

5. I let the thermometer dry before I use it again.

Tip: I clean my thermometer after every use. This keeps germs away from my family.

What to Use	What Not to Use
Soft dry cloth	Water
Rubbing alcohol	Soap
Cotton swab	Bleach

Storage

I store my thermometer in a safe, dry place. 🏠

Here is how I keep it safe:

• I put the thermometer back in its case after I use it.

• I keep it in a drawer or on a shelf, away from sunlight.

• I never leave it in the bathroom or near water.

• I do not put heavy things on top of it.

Note: If I travel, I take the thermometer in its case. This stops it from breaking.

Good places to store my thermometer:

• Bedroom drawer

• Medicine cabinet (not in the bathroom)

• High shelf, out of reach of small kids

Battery Care

I check the batteries often to make sure my thermometer works. 🔋

Here is what I do:

1. I look at the screen. If it shows a low battery sign, I change the batteries.

2. I use the type of battery the manual says. Most Braun ear thermometers use AA or AAA batteries.

3. I take out the batteries if I will not use the thermometer for a long time.

4. I put in new batteries the right way. I look for the plus (+) and minus (–) signs.

5. I throw old batteries away in a safe place, not in the trash.

Alert: If the thermometer does not turn on after I put in new batteries, I check if they are in the right way. If it still does not work, I ask for help.

Battery Tip	Why It Matters
Use right battery	Keeps thermometer working
Remove if not in use	Stops battery leaks
Check for rust	Rust can break thermometer

I always take care of my thermometer. This helps it last a long time and keeps my family healthy! 😊

• My thermometer always shows the wrong temperature, even after I clean it and use it right.

• The probe window looks dirty or broken, and I cannot clean it.
